The Hotel is nice, simple but comfortable, with fairly large rooms.
The breakfast (not included in price) is good and there are many plants of options to choose.
The best thing here is that the hotel is managed by some young guys who are really kind and that can speak all fluent english (something not for granted in Brazil).
BE AWARE OF THE TOURS!
Within the hotel there is a Tour Operator offering daily trips to both Falls sides (the Brazilian and Argentina one) but they are not completely transparent.
First, you can easily arrange Tours yourselves, taking Public buses and saving some money (mainly the one on the Brazilian side, which is very easy to plan, and also Uber is an option, because they effectively just offer you the transportation to the Park entrance).
However, if you want to do the tours with them, mainly the one in Argentina, pay attention to the money change. I'm, telling you this 'cause they tell you that they will drive you to a Money Change place before entering Argentina because they do no accept Reais and there is no place to withdraw money...COMPLITELY UN-TRUE!
First, at the Argentina Park entrance there is a Cash Machine where you can withdraw money. Then, you can pay the boat tour (which definitely should be made on this side) with credit cards, as also your lunch and snacks. Moreover, if you want to change money, there are some money change in Foz do Iguazu which are more advantageous. Indeed, I think they might have an agreement with the change agency where they drive you to, since the change here is 0,17 Reais for 1 Peso. While there are Money change in the city, for example the one 300mt from the Hotel inside the Super Market, which offers 1 Peso for only 0,12 Reais.
Therefore, whatever the tour you decide to have, pay attention to other offers and solutions.
Still, the Hotel is a good money-quality compromise, and is not to far from the most central part of the city.
